Blasting and Vibration Sound from Silencer

From past few day's I'm getting a blasting sound from silencer along with a vibration of the car as soon as I start and i give throttle in the morning when the car is cold, and this sound goes away after sometime when car heats up and also doesn't come whole day. Comes only in the morning. How can i show it to mechanic as this sound only comes in the morning. Sound from Silencer feels like as its been broken but the silencer is ok. What may be the cause of it?

Abhismarty, it might be the engine misfiring early in the morning, please get the spark plugs checked. Another thing I can think of is the fuel injectors and a unclean air filter, if the fuel injectors are unable to give enough fuel during the initial cranking up due to deposits the car might vibrate sort of as if it is gasping for fuel and if the air is unclean the combustion can suffer as well. If you are from Mumbai, I suggest that you visit Milestone in Parle, they are the authorised M&M workshop, you can meet Mr. Ajay Dalvi and the service advisor is Jeson , technician Mr. Pramod.

Hi Sid,
Thanks for the feedback. Well, yes the sound is still coming in the morning and vehicle vibrates. Checked by the local mechanic guys and are unable to find the solution. One says your engine brackets(rubber padding or something) is old and needs to be replaced, other one says your shockers also have some rubber grip which need to be changed.
The sound and vibration only comes initially while in 1st and 2nd gear, then lessen up a light or when it runs some kms in day.
I'll ask the guy to check the fuel injectors and air filter as suggested.
Thanks again.

I would not worry about it ! Honest Mine also has a vibrating noise for about 5 minutes when cold which vanishes ..This is even louder when very cold But I have had this for about 4 years ! I think its just a exhaust thing Just turn up the radio ! and don't forget a Diesel is known to be a bit temperamental when cold
